Cu: Descriptive Data Error; Cu: Configuring Data Invalid; Cu: It Is Not Possible To Write To File - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
14: Drive status cannot be changed to "ready for operation" (p0947 and p0949).
15: Drive status cannot be changed to drive download.
16: Device status cannot be changed to "ready for operation".
17: It is not possible to download the topology. The component wiring should be checked, taking into account the var-
ious messages/signals.
18: A new download is only possible if the factory settings are restored for the drive unit.
19: The slot for the option module has been configured several times (e.g. CAN and COMM BOARD)
20: The configuration is inconsistent (e.g. CAN for Control Unit, however no CAN configured for drive objects A_INF,
SERVO or VECTOR ).
Remedy: - use the current version of the commissioning software.
- modify the offline project and carry out a new download (e.g. compare the number of drive objects, motor, encoder,
power unit in the offline project and at the drive).
- change the drive state (is a drive rotating or is there a message/signal?).
- carefully note any other messages/signals and remove their cause.
201044 <location>CU: Descriptive data error
Message value: %1
Drive object: All objects
Reaction: OFF2
Acknowledge: POWER ON
Cause: An error was detected when loading the descriptive data saved in the non-volatile memory.
Remedy: Replace the memory card or Control Unit.
201045 <location>CU: Configuring data invalid
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: An error was detected when evaluating the parameter files PSxxxyyy.ACX, PTxxxyyy.ACX, CAxxxyyy.ACX, or
CCxxxyyy.ACX saved in the non-volatile memory.
Alarm value (r2124, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: Restore the factory setting using (p0976 = 1) and re-load the project to the drive unit. Operation without any restrictions
is then possible.
After downloading the project, save the parameters in STARTER using "Copy RAM to ROM" or with p0977 = 1. This
overwrites the incorrect parameter files in the non-volatile memory.
201049 <location>CU: It is not possible to write to file
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: It is not possible to write into a write-protected file (PSxxxxxx.acx). The write request was interrupted.
Alarm value (r2124, interpret decimal):
Drive object number.
Remedy: Check whether the "write protected" attribute has been set for the files in the non-volatile memory under .../USER/
SINAMICS/DATA/...
When required, remove write protection and save again (e.g. set p0977 to 1).
